	DESCRIPTION:	Declare the function published interface to layers
					note: This interface is a facade over disparate property sets on layers:
					
					1) Node-based properties:
					it currently spans the traditional INode properties and the GI properties.
					This is a convenience interface and provides only control of "coarse" properties:
					those access iconically in the layer UI.
					
					2) Additional properties unique to layers: Current.

					3) membership
											 
	CREATED BY:		John Hutchinson

	HISTORY:		created Aug 6, 2001
					add		Aug 9, 2001		add interface for layermanager
					add		Sept 3, 2001	adding properties for color and GIExclusion
